Waiting Period Types
The three main waiting periods in a health policy — initial, specific-disease and pre-existing disease — the 36-month ceilings in force since 1 April 2024, and what happens to them on portability, on a higher sum insured and on a lapse.
What a waiting period is
A waiting period is the time after a health policy starts during which certain claims are not payable. It exists so that cover is not bought only when treatment is already expected and then claimed on straight away, at the expense of everyone else in the pool. Waiting periods are counted over continuous cover, so they keep running through each renewal made without a break.
The three types
The initial waiting period runs from the start of a new policy and is usually 30 days. Illness claims arising in it are not payable. Accidental injuries are usually excepted, so a road-accident injury in the first month is payable under such a policy; the policy wording decides.
The specific-disease waiting period applies to conditions listed in the policy, usually planned or common surgical conditions such as cataract, hernia, piles and kidney or gall stones. It applies whether the condition is newly diagnosed or not. The period for each listed condition is whatever the policy states, up to the 36-month maximum.
The pre-existing disease (PED) waiting period applies to conditions the insured already had when the policy began. Once it has been served, those conditions must be covered.
The ceilings today
Under IRDAI rules in force since 1 April 2024, neither the specific-disease nor the PED waiting period can exceed 36 months of continuous cover. The earlier ceiling for pre-existing disease was 48 months, which older material still quotes.
Thirty-six months is a maximum, not a standard. Many policies set shorter periods, and the period for each listed condition is whatever the policy states.
Portability, increases and lapses
On porting to another insurer, credit for waiting periods already served with the old insurer is carried forward, to the extent of the sum insured being ported. Waiting periods apply afresh to any increase in the sum insured.
A lapse undoes the credit. If a policy is not renewed within the grace period and a new one is bought later, all the waiting periods start again from the beginning. This is also one reason people buy health insurance while young and healthy: the waiting periods are then complete before cover for those conditions is likely to be needed. Whether and what to buy still depends on individual circumstances.
Rules at a glance
Three claims in the first year
Illustration: Gurpreet buys a policy with a 30-day initial waiting period and, for cataract, a two-year specific-disease waiting period, as his policy states. In the third week he is hospitalised with a fever: not payable, because it falls in the initial waiting period. In the same week his wife, insured under the policy, fractures an arm in a road accident: payable, because his policy excepts accidents from the initial waiting period.
Six months in, he is diagnosed with cataract and advised surgery. The claim is not payable: cataract is on the policy's list and the two years have not run, whether or not the condition was pre-existing.
What a lapse costs in months
- Assumptions, for arithmetic only: a policy with a 36-month PED waiting period has been renewed without a break for 20 months.
- Months still to be served if cover continues = 36 − 20 = 16.
- The policyholder misses the renewal and the grace period, and buys a new policy 2 months after expiry, also with a 36-month PED waiting period.
- Months to be served under the new policy = 36, counted from its start.
- Extra waiting caused by the lapse = 36 − 16 = 20 months, in addition to the 2 months without any cover.
Result. Instead of 16 more months, the pre-existing condition is covered only after 36 more months from the new policy's start: the 20 months of credit already earned are lost.
Key points
- The initial waiting period is usually 30 days and usually does not apply to accidental injuries; the policy wording decides.
- The specific-disease waiting period covers conditions listed in the policy, whether newly diagnosed or not.
- PED and specific-disease waiting periods cannot exceed 36 months since 1 April 2024; the PED ceiling was 48 months earlier.
- On portability, credit for periods served carries forward to the extent of the sum insured ported.
- An increase in the sum insured attracts waiting periods afresh for the increase.
- After a lapse beyond the grace period, all waiting periods start again.
Common misunderstandings
- The 36-month figure is not the waiting period of every policy: it is the ceiling, and many policies set shorter periods.
- The specific-disease waiting period is not only for old conditions: a listed disease diagnosed for the first time after the policy starts is still subject to it.
- Porting does not restart the clock: credit is carried forward, though only up to the sum insured ported.
Questions people ask
Older notes say the PED waiting period can be four years. Is that still right?
No. The ceiling was 48 months earlier; under rules in force since 1 April 2024 it is 36 months.
If the sum insured is raised at renewal, is the whole policy subject to waiting periods again?
No. Credit already earned continues for the earlier sum insured; waiting periods apply afresh only to the increase.
Does renewing a few days late always reset the waiting periods?
Not if the renewal premium is paid within the grace period the policy allows. The reset happens when the policy lapses beyond it and a new policy has to be bought.
